need help to find the Value of X

Answer:
83
Step-by-step explanation:
All sides of a triangle combined equal 180 so you would add the values you have and then subtract it from 180
Step-by-step explanation:
We know that:-
All angles of a triangle sum up to give 180°.
So, According to Question,
[tex]20 + 87 + x = 180[/tex]
[tex]107 + x = 180[/tex]
[tex]x = 180 - 107[/tex]
[tex]x = 73[/tex]
So, x = 73° is the answer.
Hope it helps :)
